- New resultsed method count_rs, returns a ::ResultSetColumn
which in turn returns a single count value
- Even better support of count with limit
+ - New on_connect_call/on_disconnect_call functionality (check
+ POD of Storage::DBI)
+ - Automatic datetime handling environment/session setup for
+ Oracle via connect_call_datetime_setup()
+ - MySQL can now be turned into a sane database by adding
+ { on_connect_call => 'set_ansi_mode' } to the connect() call
- count/all on related left-joined empty resultsets now correctly
returns 0/()
- Fixed regression when both page and offset are specified on
can also be passed an object representing the foreign row, and the
value will be set to its primary key.
-To create related objects, pass a hashref for the value if the related
-item is a foreign key relationship (L<DBIx::Class::Relationship/belongs_to>),
-and use the name of the relationship as the key. (NOT the name of the field,
-necessarily). For C<has_many> and C<has_one> relationships, pass an arrayref
-of hashrefs containing the data for each of the rows to create in the foreign
-tables, again using the relationship name as the key.
+To create related objects, pass a hashref of related-object column values
+B<keyed on the relationship name>. If the relationship is of type C<multi>
+(L<DBIx::Class::Relationship/has_many>) - pass an arrayref of hashrefs.
+The process will correctly identify columns holding foreign keys, and will
+transparrently populate them from the keys of the corresponding relation.
+This can be applied recursively, and will work correctly for a structure
+with an arbitrary depth and width, as long as the relationships actually
+exists and the correct column data has been supplied.
+
Instead of hashrefs of plain related data (key/value pairs), you may
also pass new or inserted objects. New objects (not inserted yet, see
